E 109, 014119 (2024) – Published 16 January 2024  | The limitations that thermodynamics imposes on quantum information theory are investigated in this paper, which examines an ideal gas with an internal quantum degree of freedom undergoing a cycle. By considering a demon capable of distinguishing two quantum states, the author shows that the ability to distinguish quantum states is bounded by the second law of thermodynamics. | | | | | | Editors' Suggestion Lucas Illing, Pierce Ryan, and Andreas Amann Phys. Rev. E 109, 014223 (2024) – Published 23 January 2024  | Time-delayed relay systems, systems with switches transmitting a signal with a time delay, can be found in the biological world as well as in mechanical or electrical systems. In this paper, the authors model them using second-order linear delay differential equations and analyze their solutions, finding that, for the same values of the parameters, many stable solutions coexist. | | | | | | Featured in Physics Chung-Hao Chen, Ting-Heng Hsieh, Hong-Yue Huang, Yu-Chuan Cheng, and Tzay-Ming Hong Phys. Rev. E 109, 014607 (2024) – Published 9 January 2024  | The rate at which a raft made of ants is stretched determines its properties because the ants take time to fix holes. | | | | | | Editors' Suggestion Artem Skrypnik, Katie Cole, Tobias Lappan, Pablo R. Brito-Parada, Stephen J. Neethling, Pavel Trtik, Kerstin Eckert, and Sascha Heitkam Phys. Rev. E 109, 014609 (2024) – Published 16 January 2024  | Usually, gravity causes liquid to drain out of a foam vertically, but simulations have predicted that if the foam is sheared, the drainage will be anisotropic. This paper describes an experimental verification of that prediction by neutron radiography, which shows that the vertical drainage flow is indeed deflected horizontally. | | | | | | Featured in Physics Yongfeng Zhao, Christina Kurzthaler, Nan Zhou, Jana Schwarz-Linek, Clemence Devailly, Jochen Arlt, Jian-Dong Huang, Wilson C. K. Poon, Thomas Franosch, Vincent A. Martinez, and Julien Tailleur Phys. Rev. E 109, 014612 (2024) – Published 19 January 2024  | A new technique could allow researchers to distinguish the swimming motion of a species of microorganisms without the need to track individuals within a population. | | | | | | Editors' Suggestion Michael B. Prime, Saryu J. Fensin, David R. Jones, Joshua W. Dyer, and Daniel T. Martinez Phys. Rev. E 109, 015002 (2024) – Published 26 January 2024  | This work describes Richtmyer-Meshkov experiments to measure the strain-rate sensitivity of copper in the high-rate regime. The authors extend the maximum strain rate by more than two orders of magnitude. At higher strain rates, their strength estimates show a steep increase that agrees well with extrapolations from some of the data in the literature. The work contributes to the important effort to understand how impacts can affect the strength of solids. | | | | | | Editors' Suggestion J. C. Faure, D. Tordeux, L. Gremillet, and M. Lemoine Phys. Rev. E 109, 015203 (2024) – Published 8 January 2024  | Powerful astrophysical sources are known to interact with their surroundings via extreme radiation-plasma interactions resulting from large quantities of emitted nonthermal radiation. This paper studies the physical processes involved in such interactions, combining analytical approximations with numerical simulations, and unveils a complex sequence of particle acceleration processes. | | | | | | | |
